EUREKA Series - Scame Parre S.p.A.

LIBERA Series2.2TECHNICAL FEATURESComplying with the above indications, SCAME hasrealized, in collaboration with the manufacturers ofelectric vehicles, a connection system consisting ofa stationary socket, a movable plug and a movablesocket, with the following features:- rated current: 16A- rated voltage: 230V- number of poles 2 + ground +1 back-up terminal- protection degree: IP44- high mechanical strength- protection against direct contact by means ofprotection guards (same as for domestic plugs).The decision to design a connector which is notcompatible with existing plugs is based on thefollowing safety considerations:a) electric vehicles, in general, have the batterycharger on board, to enable recharge fromdifferent sources, without any dedicatedequipment. Battery chargers includesemiconductor devices to rectify the electriccurrent; in case of failure, these may generate faultcurrents whose wave shape is influenced by directcurrent elements. Such d.c. elements are detectedin a different way by the various types ofdifferential devices used in the electric systems,namely:- AC differentials, which are used the most indomestic applications, are not able to detectunidirectional currents and currents influenced bythe d.c. elements of the fault current.;- type A differentials are able to detect sinusoidalfault currents, unidirectional fault currents andcurrents influenced by d.c. elements of the faultcurrent up to 6 mA;- type B differentials are able to detect sinusoidalfault currents, unidirectional fault currents, andfault currents influenced by d.c. elements with novalue limit.The use of a connector which is not compatiblewith any existing system involves the installation ofthe new part; it is therefore assumed that the useradopting the new stationary socket takes care alsoof the proper protection against indirect contacts.b) the protection of the active pits of the socket bymeans of guards able to meet IpxxD protectiondegree is essential , especially when these socketsare installed in rooms for domestic use; actually inthis case the control on the continuity of thegrounding system may be neglected andconsequently pits could remain always active. Theprotection of active pits with proper guards notonly provides the control on the continuity of thegrounding system where required, but assuresthat no solid foreign matter is introduced into theseat of active pits.These new connectors will be used first in somepublic areas for the recharge of motorcycles, whichhave been arranged in Rome on the occasion ofthe Jubilee.The manufacturers, installers and users of electricvehicles will find the new product at electricwholesalers distributing SCAME materials.MANUFACTURING SPECIFICATIONS-Grey handgrip - color specification RAL 7035- Guiding slit fitting different cable diameters(there is no need to cut or match the guiding slit)- Sockets with spring cover and holding devicewhen plug is connected- Quick connection and disconnection between thehandgrip and the fruit by means of patentedSNAP-ON device- All the screws of the terminal and of the cableholderare oriented in the same direction- The cable-holder is balancing and provided withlock-Ergonomic handgrip to favor easy grip and use- High protection from indirect contacts, since theground contact is the first to be established andthe last to separate- Standardized color, depending upon the voltageused.SNAP-ON DEVICEQuick release opening and closureA proper patented SNAP-ON device assures thequick release connection and disconnection of theEUREKA series sockets and plugs.The SNAP-ON device reduces remarkably wiringtimes: in fact opening is obtained by releasing thespring with a tool and closure by a simple rotationof the handgrip or of the fruit.OPENINGThe product is supplied in the open position;opening is obtained by a simple rotation of thehandgrip or of the fruit.CLOSUREThe spring located on the side of the handgriplocks the same on the contact-holding fruit.The assembly is locked through a simple rotation,engaging the spring into its seat.INSPECTIONOpening is possible by means of a tool (screwdriver) to be used following the ideographs markedon the handgrip.Plugs andsocketsAdaptorsDomesticcablereelsLampholdersTV & PhonePlates anddevicesEnclosuresPlugs andsocketsInterlockedsocketsSwitchgearLight fittingsDistributionassembliesDomestic installation.Public recharge area.AdaptorsBesides reducing remarkably wiring times, the device enables to rapidly inspect the terminals and relevant cables on the occasionof the periodic checks of the electric system..1 Press deeply. 2 3 Rotate the fruit. 4 Draw out.Industrialcable reelsAccessoriesWire connectorsConduits31234TrunkingIndex174175
